<h4><a name = "tag_000_010_127">&nbsp;</a>NAME</h4><blockquote>
towctrans - character transliteration
</blockquote><h4><a name = "tag_000_010_128">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="wctype.h.html">wctype.h</a>&gt;

wint_t towctrans(wint_t <i>wc</i>, wctrans_t <i>desc</i>);
</code>
</pre>
</blockquote><h4><a name = "tag_000_010_129">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>towctrans()</i>
function transliterates the wide-character code
<i>wc</i>
using the mapping described by
<i>desc</i>.
The current setting of the LC_CTYPE category should be the same as
during the call to
<i><a href="wctrans.html">wctrans()</a></i>
that returned the value
<i>desc</i>.
If the value of
<i>desc</i>
is invalid (that is, not obtained by a call to
<i><a href="wctrans.html">wctrans()</a></i>
or
<i>desc</i>
is invalidated by a
subsequent call to
<i><a href="setlocale.html">setlocale()</a></i>
that has affected category LC_CTYPE)
the result is implementation-dependent.
</blockquote><h4><a name = "tag_000_010_130">&nbsp;</a>RETURN VALUE</h4><blockquote>
If successful, the
<i>towctrans()</i>
function returns the mapped value of 
<i>wc</i>
using the mapping described by
<i>desc</i>.
Otherwise it returns
<i>wc</i>
unchanged.
</blockquote><h4><a name = "tag_000_010_131">&nbsp;</a>ERRORS</h4><blockquote>
The
<i>towctrans()</i>
function may fail if:
<dl compact>

<dt>[EINVAL]<dd>
<i>desc</i>
contains an invalid transliteration descriptor.

</dl>
</blockquote><h4><a name = "tag_000_010_132">&nbsp;</a>EXAMPLES</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_010_133">&nbsp;</a>APPLICATION USAGE</h4><blockquote>
The strings - "tolower" and "toupper" -
are reserved for the standard mapping names.
In the table below,
the functions in the left column are equivalent to
the functions in the right column.
<pre>
<code>
towlower(<i>wc</i>)    towctrans(<i>wc</i>, wctrans("tolower"))
towupper(<i>wc</i>)    towctrans(<i>wc</i>, wctrans("toupper"))
</code>
</pre>
</blockquote><h4><a name = "tag_000_010_134">&nbsp;</a>FUTURE DIRECTIONS</h4><blockquote>
